The Sir John Herschel Collection
The preparation of the print Calendar of the Correspondence of Sir John Herschel (Michael J. Crowe ed., David R. Dyck and James J. Kevin assoc. eds, Cambridge, England: Cambridge Univ. Press, 1998, viii + 828 pp) which was funded by the National Science Foundation, took ten years. It was accomplished by a team of seventeen professors, visiting scholars, graduate students, advanced undergraduates, and staff working at the University of Notre Dame.
The first online version of Calendar was created in 2009 by Dr Marvin Bolt and Steven Lucy, working at the Webster Institute of the Adler Planetarium, and it is that data that has now been reformatted for incorporation into Ɛpsilon.
Further information about Herschel, his correspondence, and the editorial method is available online here: http://historydb.adlerplanetarium.org/herschel/?p=intro
No texts of Herschel’s letters are currently available through Ɛpsilon.
Sending a pamphlet on the quality of refracted light. Hopes JH will communicate it to the R.S.L.
Has now received his pamphlet. Does not agree with its findings, but will submit it to the R.S.L., though it cannot be printed in R.S.P.T. as it has already appeared elsewhere. Comments on some of EK's theories.
Thanks for his letter. Agrees that the stones of Stonehenge must have come from the neighborhood. The chips in the barrows must have come from the hewn stones of Stonehenge.
Forwarding copy of paper by Ernst F. W. Klinkerfues; EK purports to show that movement of a star toward or away from an observer will affect its refraction in an achromatic prism.
Comments against the paper of Ernst Klinkerfüss about observations of dispersed star light [see JH's 1866-2-24].
Agrees with GS's assessment of Ernst Klinkerfüss's paper [see GS's 1866-2-27].
About William Whewell's accident, and the ideas of E. F. W. Klinkerfüss on the behavior of light due to the motion of a star source.
Says William Whewell has fallen from his horse and has been injured. Thanks JH for a paper he signed for the R.S.L.
Has heard about William Whewell's accident. Hopes he will recover, but knows his advanced age may hinder this. Wishes WS to send news of progress.
William Whewell has gotten up to walk several times. The left side of his body and face is still 'not quite right.'
Reports on paper [R.S.P.T., 156, 181-] by [William] Huggins on spectra of certain nebulae with mode of determining their brightness. Doubts some presuppositions, but regards paper as fit for publication in R.S.P.T.
Corrects misinformation about refraction and dispersion of mercury ethyl and mercury methyl.
Offers to purchase scientific manuscripts for JH at a sale in London.
Makes suggestions for the solution to the three point probability problem using integrals of infinity.
Informs JH, Charles Babbage, and James South that they are the surviving original members of the R.A S. Requests JH write an account of the R.A.S.'s founding. Discusses the evidence of the 'personal will' of God in creation.
Responds to JH's criticisms of his binocular telescope plans.
Praises JH's essay 'The Yard, the Pendulum, and the Metre.' Believes C. P. Smyth's theories concerning the Great Pyramid being a standard of measurement.
Announces a committee meeting for a volunteer group.
Suggests weaknesses in BV's plans for a binocular telescope.
Cannot give advice on the artistic merits of her photographs as he is not qualified, but offers suggestions and praise on the mechanics of the art.
